I've verified my calculations and duplicated the ggee code in a short perl script. My script and my Pd patch match, but are still off from ggee.
Hey,
I've implemented the same coefficients as the ggee [lowpass] external in Pd, and can't seem to figure out where my calculations are off. The calculations are in the [pd lowpass] sub patch.
Any ideas?
